Which outcome occurs when the activation energy of a catalytic converter within an automobile exhaust system degrades?

💡 Explanation

Reduced catalyst health increases the activation energy needed; therefore, diminishing catalytic activity lowers the pollutant conversion reaction rate because precious metal surface interactions decrease, rather than exhaust modifications or entropy dominating the reaction.
